CAR-AXLE LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 286,098, dated October 2,1883,

- Application filed July 12, 1883. (No model) To all whom, it may concern.-

Be it known that I, J 'EAN F. WEBB, of Lebanon, in the county of St. Clair and State of lllinois, have invented a certain new and useful Lubricating Attachment and Guard for Axle- Boxes of Railway- Cars, of which the .following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Reference is made ment of invention.

Figure 1 is a transverse section of an oilbox containing the porous packing, and Fig. 2 is a similar view with the packing removed. Fig. 3 is a perspective view of my improve ment. Fig. 4 is a detail view of the head I. A is a rectangular base-frame fitting the bottom of the grease-chamber in the oil-box 13, the latter being of any common or suitable form. C is the axle-journal, and D the journal-box.

E are spiral springs whose lower ends are attached to the frame A, and whose upper ends are attached to the side bars, F, of the cradle, upon which the capillary packing G is supported. This cradle has curved springtongues f, shown as made in one piece with the side bars, and whose lower ends bear upon the bottom of the oil-box, the tongues f of one side bar, F, extending between those of the other, so that they form a support for the packing G, that will keep the same in contact with the journal, for as the packing becomes condensed in use the cradle will be raised by the springs E. The side bars, F, and tongues f have spurs f, that serve to hold the packing and keep it from slipping down the tongues. The base-lrame has joints (1, and the side bars joints f, to enable the easy insertion of the apparatus into the oilbox through the opening, through which the packing and oil or grease are inserted.

Attached to the inner ends of the side bars, F, are two segmental plates whose inner curve fits the axle inside the journal box. These segmental plates are marked H. They lap past each other at the lower parts, and

to the claims for statethe laps have curved slots 71 in line with each other, and through which pass guide-pins '5, extending from a head, I, supported on a spiral spring, J, whose lower end rests in a socket, K, attached to the base-frame A.

I is a pin extending down from the head I through the upper part of the spiral spring J, and whose lower end may work in the socket K. It will be understood that the spring J will force the lower ends of the plates l-l against the bottom of the axle. The upper ends of the plates H are held against the sides of the axle by springs L, which bear against the sides of the oil-box B. The guidepins i fit with the required ease in the slots to allow the plates H a free adaptation to the axle under the pressure of the springs J and L, so that as the plates wear they shall still be held in contact with the axle. These plates form a shield that prevents the escape of oil along the axle, and excludes to a great extent the entrance of dust into the oilbox, for as the oil comes in contact with the guard or shield it runs down it and drips into the oil-box, and the shield serves to close the opening between the axle and inner wall of the greasebox, thus serving to prevent to a great degree the passage of dust.

The ordinary material or any suitable material may be used for the paekingG. W'here cotton waste is used, more or less of the threads will hang down between the tongues f, and will serve to draw up the oil by capillary attraction as long as any remains in the oil-box. Ihave shown in Fig. 1 a sponge, G, placed at bottom to sustain the rest of the packing; but this is not essential, and may not be desirable, except where the packing is of such a character as to fall or work throughbetween the tongues f. I \Vithout the shield H H the movement of the cradle Ff might cause the packing to project through the space between the axle and the oil-box. It will be seen the construction of the shield would-enable it to fit against the axle in all positions of the cradle.

1. The combination, with the cradle Ff and the packing G, of the spin-sf, l'onthe purpose set forth.

2. The combination of springs E and cradle- Ff, with tongues extending past each other and resting upon the bottom of box 13.

3. The combination, with the oil-box Band 5 spring-cradle E F f, of the shield H, secured to the cradle and fitting the axle, for the pun, pose set forth.

4. The combination, with the spring-cradle, of the dust and oil shield composed of two I or more segments, II, loosely jointed and 1a ping together, and the controlling-guide I a and springs J and L, substantially as and f' the purpose set forth.
